Product details
Overview
R5F100JHDFA#V0 from Renesas is a 52-pin LQFP-0.65mm, 256 KB flash, 8 KB data flash, 20 KB RAM RL78/G13 16-bit microcontroller operating from 1.6–5.5 V, delivering 41 DMIPS at 32 MHz with ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), used in industrial sensor nodes and battery-powered HMI control panels.
For engineers reviewing the R5F100JHDFA#V0 datasheet, R5F100JHDFA#V0 pinout, R5F100JHDFA#V0 application, or R5F100JHDFA#V0 equivalent, key selection criteria include its 52-pin LQFP package, integrated RTC + LVD + BGO data flash, 10-bit 26-channel ADC, and support for LIN-compliant UART in industrial temperature grade (−40°C to +85°C).
Technical Context
The R5F100JHDFA#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz HS mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes up to 16× 16-bit timers, 1× real-time clock with calendar/alarm/correction, 3× I²C channels, 4× UART/LIN interfaces, 2× CSI/SPI, 2–4 DMA channels, and hardware multiplier/divider/MAC - all optimized for deterministic real-time control in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100JGDFA#V0 | Same 52-pin LQFP package, 128 KB flash, 8 KB data flash, 12 KB RAM - reduced memory and RAM capacity | Suitable for simpler control tasks with smaller firmware footprint and lower data logging depth | Select when application firmware fits ≤128 KB and requires only basic RTC + ADC functionality |
| R5F101JHDFA#V0 | Identical pinout and package, but lacks data flash memory (0 KB); otherwise matches core/peripheral spec | Applicable where EEPROM-like nonvolatile storage is handled externally or unnecessary | Choose when external serial EEPROM or FRAM handles parameter storage, reducing BOM cost and flash management complexity |
Compared with R5F100JHDFA#V0, R5F100JGDFA#V0 trades memory headroom for cost-sensitive designs, while R5F101JHDFA#V0 removes data flash entirely - both retain identical timing, power, and peripheral compatibility for drop-in evaluation.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating of the R5F100JHDFA#V0?
The R5F100JHDFA#V0 operates at up to 32 MHz using its high-speed on-chip oscillator and delivers 41 DMIPS (Dhrystone MIPS) at that frequency. Its minimum instruction execution time is 0.03125 μs in high-speed mode, confirmed in the RL78/G13 datasheet Rev.3.80 Section 1.1.
Does the R5F100JHDFA#V0 support LIN bus communication, and if so, which peripheral implements it?
Yes, the R5F100JHDFA#V0 supports LIN bus communication through its UART peripherals - specifically UART0 and UART1, which are LIN-compliant per ISO 17987. The hardware includes LIN-specific features such as automatic sync-field detection and break detection, enabling direct connection to LIN transceivers without software bit-banging.
What is the data flash endurance and voltage range for programming the R5F100JHDFA#V0?
The R5F100JHDFA#V0 features 8 KB of data flash memory rated for 1,000,000 write/erase cycles (typical) and programmable across VDD = 1.8 V to 5.5 V. Background operation (BGO) allows concurrent code execution during rewrites, and the flash library reserves RAM starting at address FAF00H for safe self-programming.
What package type and pin count does the R5F100JHDFA#V0 use, and what is its pitch?
The R5F100JHDFA#V0 uses a 52-pin LQFP package with 10 mm × 10 mm body size and 0.65 mm lead pitch, as specified in Table 1-1 (page 9) of the RL78/G13 datasheet R01DS0131EJ0380. The #V0 suffix confirms tray packaging for this LQFP variant.
How does the R5F100JHDFA#V0 achieve ultra-low power consumption in STOP mode?
The R5F100JHDFA#V0 achieves 0.57 μA in STOP mode by disabling the main system clock while retaining power to the real-time clock (RTC) module and low-voltage detector (LVD), both of which remain fully functional. This configuration enables timekeeping and brown-out monitoring without waking the CPU - critical for long-life battery applications.
